Application filed (lctober 15, 1904. Serial No. 228,658.

Patented Sept. 4, 1906.

To all whom it may concern.-

Be it known that we, CARY A. NEYLAND and HENRY G. N AGEL, citizens of the United States, and residents of Lewiston, in the county of Nez Perces and State of Idaho, have invented a new and Improved Current- Motor, of which the following is a full, clear, and exact description.

Our invention relates to that class of devices known as current-motors, and has for its object the utilization of the maximum amount of force that the current in any stream is capable of imparting.

With these and other objects in view our invention consists in the combination and arrangement of parts, as will be more fully described hereinafter and definitely set forth I over the water. This is accomplished by sliding the reciprocating bar 15 on the pin 21 from one end of the slot 20 to the other. In order to perform this operation automatically, the end of one of the paddles, such as 2, is connected by means of a rod 23 to a sliding member 24, which operates in a slot 25 in the bar 15. The length of the slot 25 is such that when the paddle arrives near the end of-its stroke the sliding member 24 will strike the end of the slot and push the bar 15 toward the opposite paddle, so that the pin 21 is at the opposite end of the slot 25. Since the paddle 2 is being elevated at this time by the cam 38 the yoke 12 swings backward and through its connection with the bar 15 rocks the latter upon the pin 20, whereby toswing in the claims. the yoke 13 forward to lower the paddle 3.

Reference is to be had to the accompany- The connection of the bars 16 17 with yokes ing drawings,forming a part of this specifica- 12 13 being at a higher level than their contion, in which similar characters of reference nection with the bar 15 tends to lower the indicate corresponding parts in all the views.

Figure 1 is a plan view of the current-motor, showing it connected to two pumps. Fig. 2 is a side elevation. Fig. 3 is an end view, and Figs. 4 and 5 are detail views showing the cam-surface for raising the paddles.

Our motor consists of a base 1, upon which are supported paddles 2 3. These paddles are pivotally mounted upon brackets 4 5, and these brackets are themselves mounted on vertical pivots, so that they will swing in a horizontal direction. By means of this mounting the paddles 2 3 have a universal motion about the point at which they are connected to the brackets 4 5. The paddles 2 and 3 are further supported by means of rods 6 7, which are pivotally attached to the paddles at 8 and 9 by any suitable means and also at points 10 and 11 on yokes 12 and .13. These yokes are pivotally mounted on the base, so that they can swing on a horizontal axis passing through the pivots which bear in eyes 14. The other sides of the yokes 12 and 13 are connected with a reciprocating bar 15 by means of rods 16 17 and eyes 18 and 19. This reciprocating member 15 has a slot 20, extending in a horizontal direction equal distances on each side of its center, and extending through this slot is a pin 21, mounted upon the base 1. This pin 21 has a head 22 to prevent the bar from sliding off the pin. The object of this construction is to raise and lower the ends of the paddles which project corresponding end of the bar when the yoke is swung backward.

The provision of the pin-and-slot mounting for the bar permits of a greater swing of the yoke, and as a consequence a greater vertical movement of the paddle, since the corresponding arm of the lever islengthened and shortened in synchronism with the swing of the yoke. After the paddle has been returned near the beginning of its stroke the sliding member 24 again strikes the other end of the slot 25 and returns the reciprocating bar to its original position. This operation causes the paddles to rise and fall by reason of the fact that they are connected with the ends of the bar 15 and the rods 7 17 and 6 16, respectively.

At a certain distance from the bracket 4 and on the paddle 2 is connected the end of a chain 26, which is passed around an idler 27 and connected to a block 28. At a corresponding distance from the bracket 5 and on the opposite side thereof a similar chain 29 is connected to the other addle 3 and is passed around an idler 30. T e idlers 27 and 30 are so placed that they will properly direct the block 28 for transmitting its motion to the devices intended to be operated upon. In this case there are two grammatically, which are intended to be operated by the motor. In order to connect the block 28 with these pumps, levers 31 and 32 are pivotally mounted at 33 34 on the base pumps shown dia- 1. In each end of these levers are formed slots adapted to engage pins on the block 28 and on piston-rods 36, respectively.

In order to insure the simultaneous operation of the two paddles and prevent vibration due to lost motion, they are connected by means of a rod 37, pivotally attached at equal distances on opposite sides of the brackets 4 5.

In order to aid the reciprocating bar in raising the paddles at the end of their effective stroke, earns 38 are fastened to the base 1 and made of such sha e that they will gradually raise the arms 0 the paddles 2 and 3 as they approach the end of said stroke.

Our invention it especially adapted to be used for pumping water for irrigation, but may also be used for other purposes.

While the above is one form of our invention, we do not wish to be limited to the pre cise details therein set forth, but only in so far as stated in the claims.

In operation, the motor being placed in the stream, the connection of the blades is such that one of them will be in its lowermost position and will be engaged by the current, as

shown in Fig. 2. The force of the current tends to move the blade in the direction of travel thereof, this motion bein permitted by the mounting of the blade. s the blade 3 moves toward its companion blade, its enagement with the cam 38 will tend to lift it om the water, while at the same time through its connection with the blade 2 the latter will be turned upon its pivot to move the vane part thereof upstream and into contact with the water. The connecting-bar 15 is rocked u on its pivot through its connection with t e bracket 13 when the outer end of the blade is lifted to depress the adjacent end of the bar 15 and lift the opposite end thereof and through its connection with the bracket 12 tends to lower the vane part of the blade 2 into the water.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a current-motor, the combination of a base, a plurality of paddles mounted on said base so as to have a vertical and horizontal motion, connections between said paddles so that they Wlll operate in unison, and a flexible connection between said paddles for transmitting the power produced, substantially as described.

Y 2. In a current-motor, the combination of a base, a plurality of paddles mounted on said base so as to have a vertical and horizontal motion, means for elevating and lowering said paddles automatically at the respective ends of their stroke, means for connecting said paddles so as to operate in unison, and a fflexible connection between said paddles for l transmitting the power produced thereby,

substantially as described.

3. In a current-motor, the combination of a base, a plurality of paddles mounted on said base so as to have a vertical and horizontal motion, means for elevating and lowering said paddles automatically at the respective ends of their stroke, means for connecting said paddles so as to operate in unison, and a chain connecting the paddles for transmitting the power produced thereby, substantial y as described.

4. In a current-motor, the combination of a base, a plurality of paddles mounted on said base so as to have a vertical and horizontal motion, means for elevating and lowering said paddles automatically at the respective ends of their stroke, means for connecting said paddles so as to operate in unison, and a chain, working over pulleys and connecting the paddles, for transmitting the-power produced thereby, substantially as described.

5. In a current-motor, the combination of yoke for supporting each paddle, connections between each yoke and its paddle and also between each yoke and a reciprocating bar, which is adapted to raise and lower the paddles, a connection between one of the paddles and the reciprocating bar, for operating the same, and means connecting the paddles for operating them in unison and also for transmitting power.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
